Authentic Germany mash schedule. Attempt to draw decoction from the thickest portion of the mash. Some sources recommend that each decoction amount be given a 15 minute saccharification rest at 158 F (70 C) before boiling it.
========
Yeast is 500mL of PURE SLURRY (~1600 billion viable yeast cells) repitched from 5g of munich helles, brewed 3-4 wks ago.
Watch out for equilibrium temp on acid rest (rose to 100F instead of 95F).
Go 15% bigger on all decoctions to account for transfer heat losses.
Note the higher efficiency (82% instead of 75%) from the decoction.
All pH measurements taken at 80-90F, unless stated otherwise.
First runnings: 5.35@100F; 1.096@70F
Sparge pH: 5.43@100F
Final runnings: 5.45@100F; 1.058@70F
Pre-boil, total wort: 1.079@65F; 14.5g@200
Pitched yeast 6hrs later at 48F; oxygenate for 45s per 5g carboy.This Recipe Has Not Been Rated
